Samsung Galaxy Z Flip8 (SM-F776U1) Firmware Overview
What is the latest SM-F776U1 firmware?
F776U1UEU3AZJC, released October 30, 2026 with Android 17. It is a feature update on bootloader binary 3. The archive holds 93 official builds across 21 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Z Flip8 still getting updates?
Yes. The newest build is from October 2026, and 21 of 21 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-F776U1 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 3:
- Binary 3 — since Sep 2026
- Binary 2 — since Aug 2026
- Binary 1 — since Jun 2026
A phone already on binary 3 rejects builds with a lower binary in Odin ("SW REV CHECK FAIL"), so it can go back to an earlier Android version only if that version has a binary 3 build. How to read a build number.
